From University Lecturer to Chief Academician

Liu Rongxing is a pragmatist.

He talked to Wang Hao about the research on the phone, and then sent someone over directly. By the afternoon of the next day, the person had already arrived at Xihai University.

There were three people here, one was Hu Yuqun, director of the Aerodynamic Simulation Office, another was researcher Zhao Xiaofeng, and the other was associate researcher Gao Ming.

Wang Hao and Zhang Zhiqiang entertained three people in the Mason Mathematical Science Laboratory. They greeted each other politely, and the topic quickly turned to project research.

Hu Yuqun said, "Professor Wang, we are going to create a brand new simulation system for aerodynamic characteristics."

"Is it the simulation system of the aircraft?" Wang Hao asked.

"It can be understood in this way, but we are mainly preparing for the moon landing." Hu Yuqun said, "Heavy rockets, including manned spacecraft, have a very high demand for aerodynamic simulation, and the accuracy of the current system is not enough, especially for rockets. , which is the biggest problem.”

Wang Hao was very interested, so he asked a few more questions.

Hu Yuqun also gave a brief introduction, which is actually not a secret.

The outside world knows about it.

The space agency has long had a manned moon landing project, and most of the technologies have been overcome, but there is one technology that needs a few years to break through, that is, the problem of heavy rockets.

The domestic Changzheng series has several types of launch vehicles.

But in fact, this technology still lags behind American and Xiongguo, because the country has not yet developed a heavy-duty launch vehicle.

If it is to carry out manned landing on the moon, it is necessary to create a heavy-duty rocket that can carry a manned spacecraft, has a high enough load, and is fast enough.

Such a rocket is expected to take several years to manufacture.

Before the rocket is actually launched, a lot of simulation tests are required. They must upgrade the original aerodynamic characteristics simulation system to be able to perform higher-precision simulations on the computer.

That's the big problem.

Their original simulation system of aerodynamic characteristics is already very complete, and the accuracy of the algorithm involved in upgrading it.

The accuracy of the algorithm is not simply a matter of program logic, but is directly related to the underlying mathematical logic.

To put it bluntly, this research is to simulate the launch of a rocket, and the most difficult part is the calculation of the aerodynamic problem.

The bottom layer is still the operation problem of partial differential equations.

Hu Yuqun said, "We first approached the Institute of Aerospace Aerodynamics and wanted them to do the algorithm part."

"However, they also said that the underlying calculation is still difficult, and it is very difficult to make a breakthrough."

"If you just upgrade the program, the effect will definitely not be ideal. To put it bluntly, we need higher computing precision."

"I heard from the Shencheng Power Institute that you gave a lecture there, which is directly related to the calculation of aerodynamics. Xihai University has built a new computer laboratory, and you are the direct person in charge, so Director Liu asked me to ask. you……"

"Look at this..."

Wang Hao did not answer directly, but asked about the details, "The simulation system you mentioned, the general peripheral programs, we can definitely do, but the core algorithm, you still have to talk about it in detail before I can confirm it."

Hearing what Wang Hao said, Hu Yuqun was relieved.

He is most worried that the other party will agree without understanding.

At that time, the project will not be completed, and the cost of funds will still be a small problem. Time cannot be delayed, and their research must keep up with the progress.

This time it was Zhao Xiaofeng and Gao Ming who were very familiar with the aerodynamic simulation system and participated in the construction of the core algorithm.

Zhao Xiaofeng said, "Actually, it is still an equation analysis problem. We need to find a general algorithm in complex equations, and the conclusions drawn by this algorithm must be close to reality."

"For example, the conditions of each part of the rocket are different. Many parameters need to be input, and the density of the atmosphere must also be considered, and even the situation of encountering special clouds needs to be considered."

"There are many associated parameters, which will form a lot of complicated calculations. Some equations cannot be solved. Even if they can be solved, the process is too complicated, and there is no way to use a fixed program to get the result."

"In the aerodynamic simulation, most of them are approximate calculations, which involve the problem of deviation value, and we need higher calculation accuracy."

"That's what the core algorithm primarily solves."

Hu Yuqun added, "As long as the core algorithm can be completed, the other requirements are not high. It is enough to output images and numerical data normally. It is not necessary to make the whole system, but to make the part related to the core algorithm. Others, we have other departments to complete."

Wang Hao understood it this time, and after thinking about it, he knew it could be done.

This project was found for his research.

In fact, it is the same.

At first, Liu Rongxing wanted to find an aerodynamic research institution to complete this project. Later, he learned that Wang Hao had made a new research, which could approximate and solve partial differential equations, and could continue to approximate.

In addition, Wang Hao is also an internationally recognized top algorithm expert, and he has personally developed two very influential new algorithms.

In this way, it is natural to find Wang Hao as the core algorithm to be stable. As for the programming related to the core algorithm, it is a small problem.

So Liu Rongxing didn't even consider the size of the Mason Mathematical Sciences Laboratory.

Wang Hao agreed, "From what you say, there should be no problem. I have been doing this research."

"You guys require high precision for aerodynamic calculations, but because it is a general-purpose calculation, it is only used for simulation, and it must not catch up with the precision of top-level fighter design."

This is the truth.

The calculation accuracy in the aerospace field is higher, but the use of computers for simulation will involve the problem of general calculation, so there is no way to require too high accuracy.

Wang Hao continued, "On the issue of precision, when we are working on the core algorithm, we will definitely discuss it with you, and there should be no problems with other issues."

Several people discussed for a while, and the topic turned to the issue of funding.

Hu Yuqun negotiated the price as soon as he opened his mouth, "10 million, this has already been determined."

He continued bluntly, "The funding period is one year. If it is not completed after one year, we can only withdraw the funding, but if it is completed, the funding will not be recovered."

This is the horizontal 'lump sum project'.

Within the specified time, as long as the project can be completed, the funds will belong to the research and development party, but if the project cannot be completed, the funding can only be withdrawn.

Wang Hao thought about it, and didn't even raise the price because there was no room left.

This project is not small, and it takes more than a dozen people to work on it for a few months, but as far as the core algorithm is concerned, he can complete it by himself, but he needs to do some research and thinking.

The system engineering department bought the core algorithm.

A dozen people work for a few months, and each person is paid a salary of 100,000 yuan. Two million yuan is enough, and the labor cost is so much.

Of the 10 million funds, most of them will be left over.

So there is no room for price increase.

...

Wang Hao and Zhang Zhiqiang discussed the new project together. In fact, it was the project delivered to the door.

They nod, and the project is done.

It's that simple.

After the three of Hu Yuqun left, Zhang Zhiqiang was still in a daze, with a face full of disbelief, "So, we talked about a 10 million project?"

"yes."

"It seems easy?"

"Um."

"We are so good..."

Zhang Zhiqiang wanted to boast, but he stopped talking. Thinking about it carefully, he seemed to have started to entertain people, and at the end gave them off. He also spoke in the middle, but it was completely irrelevant to the key issue.

He talked about the project and didn't make any contribution at all.

But mainly...

The other party is not interested in him at all!

The two walked out of the director's office together, and saw Zheng Yaojun approaching, and asked, "What did those three people come for?"

"Send the project." Zhang Zhiqiang said very flatly.

"Send an item? Is there such a good thing? What item?"

"Ten million items."

"..."

After hearing this, Zheng Yaojun opened his mouth slightly, but didn't close it for a long time, "Ten million, are you kidding?"

"Can I be joking?" Zhang Zhiqiang said excitedly, "Just now we have discussed a project worth 10 million yuan, so go get ready, we're going to get busy."

Zheng Yaojun looked at Wang Hao in a daze.

Wang Hao nodded and said, "Professor Zheng, let's get ready. There are only three people in our lab now, so I will assign work."

"En, en." Zheng Yaojun has not fully digested the information.

Zhang Zhiqiang became very serious.

"Professor Zheng, you are in charge of connecting projects with the system engineers of the space agency, especially the part of the core algorithm. If they have any requirements, you must write them down in detail."

The reason why Zheng Yaojun is in charge of the docking is that he is a professor of mathematics and an expert in the field of partial differential equations.

Wang Hao looked at Zhang Zhiqiang, "Zhang Zhiqiang, you are in charge of recruiting people. Our lab needs to expand its manpower. You know more about work other than core algorithms than I do. Let's study how many people we need."

"We still have several researcher places in our laboratory, and there will be postdoctoral places in the next year. You can make a decision according to the situation."

"I hope to settle everything before the end of the year, and start to invest in this project after the end of the year. I hope that it can be completed within half a year, and it should not exceed eight months at most."

"good!"

"knew……"

...

After Wang Hao assigned the work, he checked the time and went to the restaurant for dinner.

He said he was nervous when he received a big project, but he was mainly responsible for the core algorithm and overall arrangement, and other matters, including laboratory recruitment, were all handed over to Zhang Zhiqiang and Zheng Yaojun.

At this time, he also felt that there was no one available under his command, and he really needed to temporarily expand the manpower after taking on a big project.

When we got to the restaurant, we happened to run into Xia Guobin.

He sat with Xia Guobin.

Wang Hao was also concerned about the project of Navitas Lab, "How about the project that you cooperated with Chuangwei Group?"

Xia Guobin said with a smile, "It went very well. Just last month, we have reduced the accuracy to 0.2 microns."

"Congratulations!"

The progress Xia Guobin said is indeed worthy of congratulations.

As long as the accuracy can be reduced to 0.1 microns, the project can be said to be a great success. A new microsphere screening method has been developed, which can allow domestic enterprises to master the microsphere screening method.

This technology has been monopolized by Japanese companies, and the international microsphere manufacturing market has billions of dollars.

It is definitely something worth celebrating that Navitas Lab can break the technical barrier.

Xia Guobin shook his head and said, "I'm not worried about this project, but now I'm worried about the next project."

"We can continue to cooperate with Chuangwei Group, but they have no suitable research and development projects for the time being."

"So we want to apply for the project of the Institute of Aeronautical Materials, and we don't know if we can get it. Now the microsphere project has entered the late stage, and many people in the laboratory are idle."

"There's nothing to do!"

Xia Guobin smiled wryly, "If you can't apply for the project of the Institute of Aeronautical Materials, you will probably be free for a few months."

Idleness is not a good thing for any scientific researcher.

Xia Guobin is in charge of an entire laboratory, and dozens of people are all idle, which is tantamount to wasting scientific research life.

Wang Hao shook his head and said, "I'm also worried now!"

"What are you worried about?"

"It's also a matter of the laboratory, and it's also a matter of the project."

"Ah?" Xia Guobin immediately realized, "You are talking about the Mason Mathematical Science Laboratory, isn't it built yet?"

"But the project already exists."

Wang Hao said dejectedly, "I also took on a project just now, 10 million yuan, but it turned out that there is no one in the laboratory, there is no project, but no one!"

"Oh~~~"

He heaved a long sigh.

Looking at the sad face facing him, Xia Guobin pulled the corners of his mouth vigorously.

Empty project no one?

This is too irritating!

...

Mason Mathematical Sciences Laboratory is busy with new projects.

The physics lab is also preparing new projects.

Wang Hao is the main person in charge of the two projects. On the contrary, he is free, because all the work will be done by other people, and he only needs to wait for the project to start.

He still sits in the Mason Number Laboratory, and occasionally handles some personnel work, which is the "recruitment" issue of the laboratory.

In fact, there are very few cases that require Wang Hao to deal with them personally. Most of them are Zhang Zhiqiang talking about the personnel, and Wang Hao agrees after simply asking.

Some need to be handled by him personally, such as a doctoral supervisor who wants to join.

Professor Qi Xiao.

Qi Xiao is a researcher in the computer laboratory and a doctoral supervisor in the School of Information. Hearing that the Mason Number Science Laboratory has received a horizontal project worth tens of millions of dollars, he decided to take the doctoral students from the sixth floor to the fourth floor.

Anyway, just join in.

The remuneration of the computer lab is indeed very good, but they don't have a big project, and there are only two small projects with hundreds of thousands of dollars for the time being, and the funds are very limited.

If he can join the Mason Mathematical Science Laboratory, he and his doctoral students will help with the project, and funding will naturally not be a problem. At that time, all students can be subsidized.

Employees in society will change jobs, and researchers in laboratories will also change jobs.

It is not unacceptable to move from the sixth floor to the fourth floor, and the temptation to work in a new laboratory next year is too great.

So, Qi Xiao came.

This made it difficult for Wang Hao. Of course, he hoped that Qi Xiao could come, because Qi Xiao didn't come by himself. He also had several doctoral students in informatics under him, and he could bring several people with him.

but……

"Does Dean Chen agree?" Wang Hao asked Qi Xiao in a low voice.

"I didn't ask, it's fine if you agree anyway." Qi Xiao seemed to have no pressure on his betrayal, "Anyway, it's just from the sixth floor to the fourth floor, all the same, all the same!"

"……Fine!"

Wang Hao considered Professor Qi Xiao's ability and the serious lack of personnel in the laboratory, and agreed.

As for Dean Chen Qinghua...

I'm sorry, there is no way for a good bird to choose a tree to live in.

After dealing with this matter, Wang Hao continued to do his own research. Taking advantage of this free time, he began to summarize the new research on the NS equation.

Mathematics research requires a quiet environment.

Wang Hao and Zhang Zhiqiang said not to bother them all the time, so they put up a 'Do Not Disturb' sign at the door of the office, and began to concentrate on research.

He also occasionally mentors students.

Most of the students don't need guidance, including Helen, they are all in the process of learning and accumulating, and enriching their basic knowledge can lay a solid foundation for future research and development.

Qiu Hui'an is a special one. He studies Legendre's conjecture while studying.

Wang Hao is also very concerned about Qiu Hui'an's research progress. Qiu Hui'an is using the method of group theory, combined with mathematical analysis, hoping to prove Legendre's conjecture.

In this regard, Wang Hao has not thought about it.

Wang Hao didn't intend to think about it carefully, he just occasionally raised his own suggestions, and would also discuss his ideas with Qiu Hui'an.

This is what a mentor should do.

If it is directly involved in the research, it is likely to be completed soon. Legendre conjectures that this level of research does not mean much to Wang Hao.

So it is better to let the students do their own research and cultivate their spirit of research and exploration.

On this day, Wang Hao also found Ding Zhiqiang. He tested Ding Zhiqiang's learning progress and was very satisfied with the test results.

So he rewarded Ding Zhiqiang with a textbook——

"Nonlinear Functional Analysis".

"You still need more foundations in the direction of mathematical analysis. Nonlinear functional analysis is a step further than functional analysis, which is very suitable for you to learn."

"in addition……"

Wang Hao suddenly thought of a question, "You should be ready to take the postgraduate entrance examination, right? Take the mathematics department. As long as you can pass the line next year, don't worry, just apply for my graduate degree."

Ding Zhiqiang wanted to cry.

Of course he has a plan to take the postgraduate entrance examination, but he originally planned to take the postgraduate entrance examination of informatics.

But in the past year, he didn't do anything, and devoted himself to the study of mathematics. He wanted to take the postgraduate entrance examination of informatics and had to review it again.

Math is different.

There is no problem with other basic courses, and the professional courses of mathematics have become very simple for him.

Hearing Wang Hao's words now, Ding Zhiqiang didn't know whether to cry or laugh, because everything didn't match his own plan.

He didn't even know why he suddenly wanted to major in mathematics.

Ding Zhiqiang went back with confusion.

He knew that his life had completely changed at this moment, and at the same time he felt that his future was bleak.

Department of Mathematics?

That is the realm of geniuses. He is a very ordinary student, majoring in mathematics, what future can he have?

Want to be a math teacher in the future?

...

Wang Hao didn't know Ding Zhiqiang's confusion. He also thought that Ding Zhiqiang's talent was very good, at least he learned the basics very quickly.

He devoted himself to the research of the NS equation, but he was stuck in the final stage of the research, and the reaction in the system was the stagnation of the inspiration value——

[Inspiration value: 59. 】

Wang Hao has already figured out the rules. For S+ level tasks, 20 o'clock is a research stage.

Now it is only the last point, but it has not risen for a long time.

"Oh~~"

He sighed long, thinking about the way to break through.

The door rang.

Wang Hao frowned and shouted, "Come in", and saw Zhou Qingyuan standing outside the door.

He hurriedly stood up and said, "Mr. Zhou, why are you here?"

"do not you know?"

Zhou Qingyuan walked in and asked in surprise, "Yesterday there was a big news in the mathematics world."

"What news?"

"It's related to the NS equation. Aren't you doing this research? The journal "Basic Mathematics and Applied Mathematics" published a paper that denied the smoothness of the NS equation under normal values."

"Disprove the NS equation problem?"

"That's not true." Zhou Qingyuan said, "It is because the NS equation solution set is allowed to be rough, and the output of the equation will be very unreasonable. To a certain extent, it proves that the NS equation solution set may not have smoothness."

Wang Hao thought about it and said, "Isn't this logic rigorous?"

Zhou Qingyuan said, "The logic is indeed not rigorous enough, but the proof is very rigorous. I took a general look and found no problems."

"Being published in the journal "Basic Mathematics and Applied Mathematics" must have undergone a very careful review, and the author of the paper is Buckmaster, a professor at MIT, and a very famous expert in the field of partial differential equation applications."

"Basic Mathematics and Applied Mathematics" is one of the top academic journals in mathematics, and its ranking has been in the top ten for a long time, and it still has great authority.

Wang Hao frowned and thought for a moment, then shook his head and said firmly, "I haven't seen the proof yet, but I think the conclusion must be wrong."

"This is in direct conflict with my research!"

"impossible!"

"Are you so sure?" Zhou Qingyuan was a little surprised.

"certainly."

Wang Hao nodded affirmatively, "There must be something wrong with this proof, I'll take a look right away."
